Problem with backend - ` Trying to get property 'device_id' of non-object `

Help
1

On the dashboard it is not possible to see service status out of the sudden. When looking at the service availability-map they show just fine.

  • No service is unknown, warning or critical, all good

  • The issue came out of nowhere. It worked and then it just stopped.

  • Already tried to work backwards to figure out what causes this error since it worked before adding more nodes and service checks

  • Poller is running with new service setup, works fine and faster than cron

  • LibreNMS hostname and Specific URL are correct and also the same in config.php and .env.

  • There is no custom css, logo or favicon active

  • PHP7.4

  • all required plugins installed

  • validate gives no errors on cli nor in WebUI

  • librenms was at stable, error appeared, update to master, still the same issue
